On Basics 05: you will explore OpenPLC's Slave Devices module to expand your PLC's IOs. For this video, we will be using a Raspberry Pi, which is quite limited in number of IOs, as the main PLC running OpenPLC Runtime. The Raspberry Pi's IOs are then expanded using an Arduino Uno board connected to the Pi's USB port.
